South Waziristan is part of Pakistan's tribal region, the Federally Administered Tribal Areas. The region has seen a spike in attacks carried out by U.S. drones on what are thought to be Taliban targets.

The U.S. military in Afghanistan routinely offers no comment on reported cross-border strikes. However, the United States is the only country operating in the region known to have the ability to launch missiles from drones, which are controlled remotely.

Pakistan has complained that the attacks have killed hundreds of civilians.
